Key Words Refractory · Coeliac disease · Parenteral nutrition Abstract Refractory coeliac disease (RCD) is characterised by recurrent or persistent malabsorptive symptoms and villous atrophy, despite strict adherence to a gluten-free diet for at least 6 months and where other causes of malabsorption including malignancy have been excluded. There is limited evidence and guidance on the effective management of these patients. We describe a case of severe RCD in our hospital, with symptoms controlled effectively only by total parenteral nutrition (TPN). This 68-year-old woman initially presented to the clinic with persistent non-bloody diarrhoea and vomiting. A diagnosis of coeliac disease was confirmed with a positive tissue transglutaminase assay and histology. A strict gluten-free diet was ineffective and she represented 6 months later with 13 kg weight loss (16.7%), ongoing abdominal pain and diarrhoea, with bowels opening 16 times a day. She was oedematous, had an albumin of 12 g/l and required hospital admission. She was treated for pancreatic insufficiency and presumptively for small bowel bacterial overgrowth with no resolution of symptoms. We ruled out infectious causes and investigated for small bowel malignancy; all results were negative. Small bowel enteroscopy showed ulcerative jejunitis. She was given 5 days of TPN, following which her symptoms improved and albumin normalised. This was sustained with symptom resolution and weight gain seen at follow-up. TPN successfully and rapidly induced remission in this case. Thus, a short period of TPN should be considered as a potential component of management in patients with severe RCD. © 2014 S.

Introduction
Coeliac disease (CD) is a common autoimmune condition affecting the small bowel; it is a gluten-sensitive enteropathy in genetically susceptible individuals [1]. Gluten is a constituent of wheat and gluten-like molecules are present in related foodstuffs including barley, rye and oats [2]. CD has a reported prevalence of up to 1% in western populations [1]. Advances in clinical awareness and serological testing have influenced its prevalence over the last decade [1, 3]. It is reported 1.5 times more frequently in women compared with men and is also associated with a range of other autoimmune conditions [1, 3]. From a genetic perspective there is a strong association with the HLA-DQ2 and the HLA-DQ8 haplotype, which are expressed in over 90% of patients [1]. The pathogenesis of CD is thought to be related to an increase in intestinal permeability [4, 5] and the accumulation of gliadin in the lamina propria, which stimulates both the adaptive and innate immune responses. There is eventually enterocyte destruction and subsequent villous atrophy [6]. This manifests clinically in constitutional and malabsorptive symptoms, including diarrhoea, bloating and weight loss. The diagnosis of CD relies on clinical presentation, detection of serum IgA autoantibodies and the demonstration of villous atrophy on duodenal biopsy (in accordance with Marsh’s histological criteria) [7]. Most patients have a rapid recovery to normal health following a gluten-free diet (GFD), with improvement of symptoms seen within weeks to month [3]. In the majority, GFD induces both clinical and histological remission of the disease. The complications of this disease are related to malnutrition and an association with enterocyte-associated T cell lymphoma (EATL). We present the clinical course of diagnosis and management in a case of refractory coeliac disease (RCD). This report highlights the particular therapeutic challenges faced by this phenomenon and the potential utility for parenteral nutrition in the management of such cases. Case History
We present the case of a 68-year-old lady who developed persistent non-bloody diarrhoea and vomiting whilst travelling in India. She had a 10-day stay with her family, spending time in both urban and rural settings and drinking only bottled water and unpasteurised buffalo milk. She was treated for suspected gastroenteritis. On return to the UK, her symptoms did not resolve and she was referred to the gastroenterology team at Ealing Hospital. Her initial clinical investigations revealed a positive tissue transglutaminase assay (234 U/ml, normal range 0–10 U/ml) and normocytic anaemia (haemoglobin 10.9 g/l, mean corpuscular volume 87.1 fl). She had multiple stool cultures which were negative. Endoscopic biopsies from the second part of the duodenum showed shortened broad-based villi with an increased number of intraepithelial lymphocytes, consistent with a diagnosis of CD. She commenced a strict GFD, with a later addition of steroid therapy (budesonide). This did not control her symptoms, and when seen at follow-up (6 months after her initial presentation), she complained of worsening diarrhoea and steatorrhoea, with bowels opening up to 16 times a day. She also complained of colicky abdominal pain, significant weight loss (from 62 to 49 kg) and was noted to be peripherally oedematous up to her knees. Given the alarming rate of progression of her symptoms, she was admitted from the clinic to hospital. Clinically, we questioned whether this was progression of her CD or the

presentation of a second pathology. Her admission investigations were consistent with severe malnutrition and pancreatic exocrine insufficiency, with an albumin of 12 g/l and reduced faecal elastase of 86 µg/g. She was initially treated with a strict GFD, high-energy high-protein diet, Fresubin® energy drinks and Creon® supplementation, with no significant improvement. While she was an inpatient, we proceeded to exclude other causes of malnutrition. Indeed, stool cultures were negative for bacteria, ova and cysts; tuberculosis was excluded with a negative QuantiFERON test; she was negative for HIV and was empirically treated for small bowel bacterial overgrowth with cyclical ciprofloxacin and metronidazole, with no effect. Her imaging included a normal computed tomography of the chest, abdomen and pelvis and a magnetic resonance imaging of the small bowel showing only small bowel diverticula. Upper gastrointestinal endoscopy showed chronic gastritis (negative for Helicobacter pylori) and colonoscopy was unremarkable, with no evidence of neoplasia in her biopsies. She underwent small bowel enteroscopy at a specialist unit (fig. 1) which showed ulcerative jejunitis, consistent with severe CD. Gene array studies of the biopsies obtained from D2 confirmed polyclonal T cell receptor arrangement, further reducing the likelihood of lymphoma. Thus overall, we were unable to find a second pathology explaining her intestinal failure, leaving RCD as her diagnosis of exclusion. She was then given a short trial (5 days) of total parenteral nutrition (TPN) via a Hickman line. The TPN regimen was Kabiven 14 (day 1: 768 ml at 32 ml/h, day 2: 1,560 ml at 65 ml/h, day 3: 1,920 ml at 80 ml/h, day 4: 1,920 ml at 80 ml/h, day 5: 1,920 ml at 80 ml/h). Table 1 details the constituents of each bag of Kabiven 14. While on TPN, her fluid balance, weight and blood sugar levels were closely monitored. In addition, she had daily monitoring of her haemoglobin, sodium, potassium, calcium, phosphate, magnesium, liver function tests, urea and creatinine. Following this period of TPN, her diarrhoea and steatorrhoea settled, her peripheral oedema improved and her albumin climbed to 34 g/l. She was transferred to a specialist intestinal failure unit, where she received just 2 further days of TPN before being safely discharged back to the community. A short period of TPN thus induced remission, characterised by a complete resolution of symptoms and biochemical improvement, which were sustained at follow-up. Discussion
RCD is characterised by recurrent or persistent symptoms and villous atrophy despite strict adherence to a GFD for at least 6 months when other causes on non-responsive CD and malignancy have been excluded [3, 8, 9]. This is essentially a diagnosis of exclusion, made only after eliminating other causes of malabsorption, gluten contamination in diet and malignancy. RCD can be categorised into primary (persistent symptoms without initial response to diet) and secondary (relapse following initial response to diet) [7]. A further classification of RCD is recognised, type 1 and type 2. Type 1 RCD displays a predominantly normal intraepithelial lymphocyte population and type 2 RCD shows an aberrant population [10], whereby the intraepithelial lymphocytes demonstrate a loss of surface T cell receptor, CD3 or CD8 expression, and have a greater potential to progress and evolve into an aggressive EATL [11]. This explains the poor prognosis associated with type 2 (5-year survival between 44 and 58%), in contrast to type 1, which generally runs a benign course [12, 13]. Immunohistochemistry for our patient showed the presence of CD3 and CD8, consistent with increased phenotypically normal intraepithelial lymphocytes in type 1 RCD (fig. 2).

Following the exclusion of other causes of malabsorption such as giardiasis, topical sprue, HIV and Whipple’s disease, a diagnosis of primary RCD was confirmed in our patient. Currently there are no standardised treatment regimens for RCD due to the rarity of the condition. Clinicians are usually guided by the limited number of cases reported in the literature which have successfully responded to different managements [7]. There are a number of potential therapies already described in the literature, including the use of steroids and steroid-sparing agents such as azathioprine. In the majority of RCD type 1 cases, steroid use is effective in inducing clinical remission and mucosal recovery; however, use in RCD type 2 shows clinical response in 75%, but does not induce mucosal recovery or prevent the progression to EATL. Although majority of the literature focuses on immunosuppressive therapies for RCD treatment, nutritional support is an essential part of management which should not be overlooked. Hospitalisation is sometimes necessary to ensure dietary adherence and exclude gluten contamination. Symptomatic and histological improvement has been reported following hospitalisation for dietary monitoring [8]. Elemental and liquid diets can be used to ensure total gluten withdrawal [14]; however, malabsorption and protein-losing enteropathy can be so severe in some cases that patients may require intravenous nutritional support. Studies have shown that up to 60% of patients who were hospitalised for RCD required TPN due to severe weight loss, malnutrition, severe electrolyte abnormalities, complex nutritional deficiencies and/or steatorrhoea [12, 13, 15]. TPN has the ability to provide adequate nutrition and replacement of the necessary proteins whilst allowing time for intestinal mucosal recovery. All RCD patients would benefit from the involvement of an experienced dietician who can provide TPN regimes tailored to each patient’s requirement. In our case, the patient showed improvement with TPN. Biochemically, her albumin levels increased from 12 to 34 g/l and her haemoglobin improved from 6.7 to 12 g/dl at follow-up 6 months later. Clinically, her diarrhoea slowly subsided within 1 week of starting TPN, and her weight increased from 39 kg on admission to 43 kg at follow-up. We have described a case of severe RCD where symptoms persisted despite a strict GFD, treatment with steroids, antibiotics for small bowel bacterial overgrowth and pancreatic supplementation for pancreatic insufficiency. There is limited evidence and guidance on the most effective treatment options for RCD patients. Currently, only a strict GFD has been shown to be effective. However, our case illustrates the importance of the consideration of TPN in patients presenting with RCD; a short period of TPN in our patient induced remission of CD, enabling successful recovery, weight gain and total control of symptoms. This was sustained at follow-up. Acknowledgements

Introduction
Coeliac disease (CD) is a common autoimmune condition affecting the small bowel; it is a gluten-sensitive enteropathy in genetically susceptible individuals [1]. Gluten is a constituent of wheat and gluten-like molecules are present in related foodstuffs including barley, rye and oats [2]. CD has a reported prevalence of up to 1% in western populations [1]. Advances in clinical awareness and serological testing have influenced its prevalence over the last decade [1, 3]. It is reported 1.5 times more frequently in women compared with men and is also associated with a range of other autoimmune conditions [1, 3]. From a genetic perspective there is a strong association with the HLA-DQ2 and the HLA-DQ8 haplotype, which are expressed in over 90% of patients [1]. The pathogenesis of CD is thought to be related to an increase in intestinal permeability [4, 5] and the accumulation of gliadin in the lamina propria, which stimulates both the adaptive and innate immune responses. There is eventually enterocyte destruction and subsequent villous atrophy [6]. This manifests clinically in constitutional and malabsorptive symptoms, including diarrhoea, bloating and weight loss. The diagnosis of CD relies on clinical presentation, detection of serum IgA autoantibodies and the demonstration of villous atrophy on duodenal biopsy (in accordance with Marsh’s histological criteria) [7]. Most patients have a rapid recovery to normal health following a gluten-free diet (GFD), with improvement of symptoms seen within weeks to month [3]. In the majority, GFD induces both clinical and histological remission of the disease. The complications of this disease are related to malnutrition and an association with enterocyte-associated T cell lymphoma (EATL). We present the clinical course of diagnosis and management in a case of refractory coeliac disease (RCD). This report highlights the particular therapeutic challenges faced by this phenomenon and the potential utility for parenteral nutrition in the management of such cases. Case History
We present the case of a 68-year-old lady who developed persistent non-bloody diarrhoea and vomiting whilst travelling in India. She had a 10-day stay with her family, spending time in both urban and rural settings and drinking only bottled water and unpasteurised buffalo milk. She was treated for suspected gastroenteritis. On return to the UK, her symptoms did not resolve and she was referred to the gastroenterology team at Ealing Hospital. Her initial clinical investigations revealed a positive tissue transglutaminase assay (234 U/ml, normal range 0–10 U/ml) and normocytic anaemia (haemoglobin 10.9 g/l, mean corpuscular volume 87.1 fl). She had multiple stool cultures which were negative. Endoscopic biopsies from the second part of the duodenum showed shortened broad-based villi with an increased number of intraepithelial lymphocytes, consistent with a diagnosis of CD. She commenced a strict GFD, with a later addition of steroid therapy (budesonide). This did not control her symptoms, and when seen at follow-up (6 months after her initial presentation), she complained of worsening diarrhoea and steatorrhoea, with bowels opening up to 16 times a day. She also complained of colicky abdominal pain, significant weight loss (from 62 to 49 kg) and was noted to be peripherally oedematous up to her knees. Given the alarming rate of progression of her symptoms, she was admitted from the clinic to hospital. Clinically, we questioned whether this was progression of her CD or the

presentation of a second pathology. Her admission investigations were consistent with severe malnutrition and pancreatic exocrine insufficiency, with an albumin of 12 g/l and reduced faecal elastase of 86 µg/g. She was initially treated with a strict GFD, high-energy high-protein diet, Fresubin® energy drinks and Creon® supplementation, with no significant improvement. While she was an inpatient, we proceeded to exclude other causes of malnutrition. Indeed, stool cultures were negative for bacteria, ova and cysts; tuberculosis was excluded with a negative QuantiFERON test; she was negative for HIV and was empirically treated for small bowel bacterial overgrowth with cyclical ciprofloxacin and metronidazole, with no effect. Her imaging included a normal computed tomography of the chest, abdomen and pelvis and a magnetic resonance imaging of the small bowel showing only small bowel diverticula. Upper gastrointestinal endoscopy showed chronic gastritis (negative for Helicobacter pylori) and colonoscopy was unremarkable, with no evidence of neoplasia in her biopsies. She underwent small bowel enteroscopy at a specialist unit (fig. 1) which showed ulcerative jejunitis, consistent with severe CD. Gene array studies of the biopsies obtained from D2 confirmed polyclonal T cell receptor arrangement, further reducing the likelihood of lymphoma. Thus overall, we were unable to find a second pathology explaining her intestinal failure, leaving RCD as her diagnosis of exclusion. She was then given a short trial (5 days) of total parenteral nutrition (TPN) via a Hickman line. The TPN regimen was Kabiven 14 (day 1: 768 ml at 32 ml/h, day 2: 1,560 ml at 65 ml/h, day 3: 1,920 ml at 80 ml/h, day 4: 1,920 ml at 80 ml/h, day 5: 1,920 ml at 80 ml/h). Table 1 details the constituents of each bag of Kabiven 14. While on TPN, her fluid balance, weight and blood sugar levels were closely monitored. In addition, she had daily monitoring of her haemoglobin, sodium, potassium, calcium, phosphate, magnesium, liver function tests, urea and creatinine. Following this period of TPN, her diarrhoea and steatorrhoea settled, her peripheral oedema improved and her albumin climbed to 34 g/l. She was transferred to a specialist intestinal failure unit, where she received just 2 further days of TPN before being safely discharged back to the community. A short period of TPN thus induced remission, characterised by a complete resolution of symptoms and biochemical improvement, which were sustained at follow-up. Discussion
RCD is characterised by recurrent or persistent symptoms and villous atrophy despite strict adherence to a GFD for at least 6 months when other causes on non-responsive CD and malignancy have been excluded [3, 8, 9]. This is essentially a diagnosis of exclusion, made only after eliminating other causes of malabsorption, gluten contamination in diet and malignancy. RCD can be categorised into primary (persistent symptoms without initial response to diet) and secondary (relapse following initial response to diet) [7]. A further classification of RCD is recognised, type 1 and type 2. Type 1 RCD displays a predominantly normal intraepithelial lymphocyte population and type 2 RCD shows an aberrant population [10], whereby the intraepithelial lymphocytes demonstrate a loss of surface T cell receptor, CD3 or CD8 expression, and have a greater potential to progress and evolve into an aggressive EATL [11]. This explains the poor prognosis associated with type 2 (5-year survival between 44 and 58%), in contrast to type 1, which generally runs a benign course [12, 13]. Immunohistochemistry for our patient showed the presence of CD3 and CD8, consistent with increased phenotypically normal intraepithelial lymphocytes in type 1 RCD (fig. 2).

Following the exclusion of other causes of malabsorption such as giardiasis, topical sprue, HIV and Whipple’s disease, a diagnosis of primary RCD was confirmed in our patient. Currently there are no standardised treatment regimens for RCD due to the rarity of the condition. Clinicians are usually guided by the limited number of cases reported in the literature which have successfully responded to different managements [7]. There are a number of potential therapies already described in the literature, including the use of steroids and steroid-sparing agents such as azathioprine. In the majority of RCD type 1 cases, steroid use is effective in inducing clinical remission and mucosal recovery; however, use in RCD type 2 shows clinical response in 75%, but does not induce mucosal recovery or prevent the progression to EATL. Although majority of the literature focuses on immunosuppressive therapies for RCD treatment, nutritional support is an essential part of management which should not be overlooked. Hospitalisation is sometimes necessary to ensure dietary adherence and exclude gluten contamination. Symptomatic and histological improvement has been reported following hospitalisation for dietary monitoring [8]. Elemental and liquid diets can be used to ensure total gluten withdrawal [14]; however, malabsorption and protein-losing enteropathy can be so severe in some cases that patients may require intravenous nutritional support. Studies have shown that up to 60% of patients who were hospitalised for RCD required TPN due to severe weight loss, malnutrition, severe electrolyte abnormalities, complex nutritional deficiencies and/or steatorrhoea [12, 13, 15]. TPN has the ability to provide adequate nutrition and replacement of the necessary proteins whilst allowing time for intestinal mucosal recovery. All RCD patients would benefit from the involvement of an experienced dietician who can provide TPN regimes tailored to each patient’s requirement. In our case, the patient showed improvement with TPN. Biochemically, her albumin levels increased from 12 to 34 g/l and her haemoglobin improved from 6.7 to 12 g/dl at follow-up 6 months later. Clinically, her diarrhoea slowly subsided within 1 week of starting TPN, and her weight increased from 39 kg on admission to 43 kg at follow-up. We have described a case of severe RCD where symptoms persisted despite a strict GFD, treatment with steroids, antibiotics for small bowel bacterial overgrowth and pancreatic supplementation for pancreatic insufficiency. There is limited evidence and guidance on the most effective treatment options for RCD patients. Currently, only a strict GFD has been shown to be effective. However, our case illustrates the importance of the consideration of TPN in patients presenting with RCD; a short period of TPN in our patient induced remission of CD, enabling successful recovery, weight gain and total control of symptoms. This was sustained at follow-up. Acknowledgements
